Research / Water Science Laboratory / International Collaboration: Japan

An important component of WSL’s research activity is international collaboration. We have been very fortunate to have met and worked closely with scientists from Shimane University, in Matsue, Japan, since 2005.

Research efforts have focused on several soil and water related areas including: heavy metal distribution in fluvial sediments (Matsumoto et al., 2010), bio-mediated sorption processes and materials to mitigate phosphorus eutrophication (Wolfe, 2009), development of watershed-scale hydrologic models (Somura et al. 2009), watershed-level environmental resource recycling (Mori et al, 2015), and secondary / college level science education (Wolfe 2015). Several AgriLife scientists have participated in symposiums at Shimane University (Dugas, 2005; Narasimhan et al., 2005; Hoffman, 2005 & 2008, Wolfe, 2008) and numerous Japanese scientists have visited the Blackland Research and Extension Center (BREC) where they have taken part in both field and laboratory investigations in such areas as: soil erosion (Mori et al. 2015), water quality (Somura, fluvial sediment contamination, and hydrologic modeling in both Texas and Japan. Two Shimane University scientists, Dr Ichiro MATSUMOTO and Dr. Hiroaki SOMURA have been particularly active with the WSL. Dr. MATSUMOTO has made more than 10 visits to Temple in the past 9 years to examine river sediments and Dr. SOMURA has made more than a dozen visits. Dr. SOMURA was able to spend one entire year at BREC (2010-2011) investigating water quality in the Leon River Watershed upon receiving a Japan Society for the Promotion of Science (JSPS) Fellowship.

Another important component of WSL’s research philosophy is personal connections. Conducting research is not just doing the field and lab work; to be successful, an investigator relies on a good bit of social interaction and cultural exchange. As an example, personal connections with the above mentioned Japanese scientists helped Dr. Wolfe obtain a JSPS/National Science Foundation Fellowship. Because of his strong inter-personal connection and their letters of support, he was able to spend ten weeks in Japan during the summer of 2009 investigating the effect of periphyton on phosphorus sorption by recycled concrete materials (Wolfe, 2009).       

After participating in the JSPS Summer Program, Dr. Wolfe joined the US-JSPS Alumni Association (http://www.jspsusa-alumni.org/).  This organization fosters collaboration among its members and their Japanese colleagues through a website, newsletters, and annual meetings.  The “Member Publications” listed under the “Member Activity” page on the web site give interesting descriptions of US-JSPS Alumni experiences.  Information and links regarding JSPS supported programs are also provided for persons interested in conducting new or continued research in Japan.
